UNITE STATES- STEPHEN PORTER, OF BOSTON, MASSACHUSETTS, ASSIGNOR TO MILTON A. KENT, OF SAME PLACE.

GLOVE-FASTENER.

SPECIFICATION forming part of Letters Patent No. 360,111, dated lVIarch 29, 1887.

Application filed December 10, 1886. Serial No. 221,163.

To all whom, it may concern.-

Be it known that I, STEPHEN Poa'rna, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachir setts, have invented certain new and useful Improvements in Glove-Fasteners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

This invention pertains to ball-andsocket fasteners, so called, and may be considered as an improvement upon and intimately related to my invention as embodied in an application filed October 13, 1886, Serial No. 216,131, the essential feature of which consists in the employment of an eyelet with a shank imperforate and longitudinally corrugated in part.

My invention is contained in the socket member of the fastening, which, in lieuof being hemispherical, as generally constructed, and notched or cut to render the perimeter of its mouth yielding, is in thepresentinstance made from a section of a cylinder, one end of which is closed and centrally perforated,while its op posite and open end is longitudinally corrugated. One-half the corrugations so formed project inwardly, and thereby contract the bore of the cylinder by double the depth of one corrugation. Thus by increasing the depth of the corrugations the mouth of the socket may be regulated in size, while the flexibility of the tube is effected thereby, more orless, according to the number of said corrugations.

The drawings accompanying this specification represent, in Figure 1, a central vertical section of a socket member of a fastening device; Fig. 2, a cross'section on line 3 y in Fig. 1, and Fig.- 3 a View similar to that in Fig. 1 of a socket member of a fastening device secured to a fabric and embodying my invention. Fig. at is a central vertical section of a buttoucap. Fig. 5 represents a modification in the button cap or fastening instrumentality, the stud being shown in broken lines.

In the annexed drawings, A represents the socket member of a fastening device adapted (No model.)

to engage and retain the stud member when thrust within it. This socketmember is preferably formed from asection of a hollow cylinder, which is to be cut of the requisitelength and closed at one end-the upperwhich is centrally perforated. When this stage in its manufacture has been reached, it is evident that the bore a is of uniform diameter throughout. To render the walls of the cylinder yielding, and at the same time contract the lower open end, I form a series of corrugations, 0 cc, 1011- gitudinally disposed,which extend only ashort distance along the imperforate metal forming the socket member. By means of said corru gations the mouth of the socketis not only contracted and rendered less in diameter than the upper remaining part of the bore a, but it is likewise made flexible and yielding suflicient to readily admit the head of the stud and then close upon and hold the latter firmly in position when it is thrust within.

Having thus described the socket member proper and its peculiar construction and novel features, I will now proceed to explain the method of securing the same to a glove or other analogous article.

Since it is desirable to give the fastening, as an entirety, a neat and tasty appearance and cause it to approximate a button in shape, I

have employed a button-shaped cap, B, (see Fig. 4,) struck up from some suitable material. This cap is centrally perforated, and is pro vided with a short tubular shank or boss, I), inwardly formed integrally therefrom, which serves as a fastening member. To firmly unite these two parts A B to the fabric, a perforation is made in the latter, and the fastening boss I) is thrust through it from the upper side. The socket member is now adjusted beneath the fabric, and the opening centrally formed in the closed end is now aligned with and receives said boss I). X'Vheu the two parts are thus properly adjusted, pressure is applied and the extremity of the boss is upset and spread out upon the inside of thesocket memher, and the latter is completely and securely attached, as shown in Fig. 3.

An evident and simple modification is represented in Fig. 5, in which, in lieu of the fastening-boss b, integrallystruck from the buttoncap, a simple fastening eyelet or rivet of some malleable metal may be employed. However, for economy in manufacture and strength of the article, I prefer the fastening-boss formed integrally from the cap 13, since by this method only two parts are required to form and attach the socket member to the material, in lieu of three or more pieces, as now generally employed.

I claim- 1. A socket member of a fastening device, composed of a hollow cup, the closed end. of which is centrally pierced, while its open or mouth end is corrugated longitudinally and thus rendered yielding, substantially as set forth.
